GOLD-SAVING- APPARATUS.

To all whom it may concern:

Be it known that I, WILLIAM II. HACK- Nnr, a citizen of the UnitedStates, residing at the National Soldiers Home, in the county of LosAngeles and State of California, have invented new and usefulImprovements in Gold-Saving Apparatus, of which the following is aspecification.

My invention relates to that class of gold separators adapted for use insituations where it is desired to separate fine gold or foreignsubstances where water covers the gold carrying gravel or debris, and ismore particularly adapted for use in running streams where line gold isfound in the gravel and dirt in the bottom of the stream; and it is ofthe objects of my invention to provide a portable separator that can bereadily moved from place to place or along up and down t-he stream. Iaccomplish this object by means of the apparatus described herein andshown in the accompanying drawings, in which z- Figure 1 is a sideelevation of my gold separator, parts broken away. Fig. 2- is afragmentary view of the apparatus showing the agitator. F ig. 3- is afront elevation. Fig. is a plan view partly broken away. Fig. 5- is adetail partly broken away of means to adjust the discharge openinfr.

I have shown my improved separator mounted on the float A in the waterB, at the bottom of which is the sand, gravel and sediment C whichcarries the fine gold to be extracted therefrom.

Referring to Figs. 1 and 3, the gravel or loose earth, clay or othersubstance carrying gold or other precious metal is sucked up through thesuction pipe 1 and is carried into the centrifugal pump 2. Motion isimparted to this pump by means of the engine 3 and water passes out ofthe pump through the discharge pipe 4 passing thence into thedistributing tank 5 through the discharge noz- Zle 6. Covering theopening at the discharge nozzle 6 I have provided a screen 7, thepurpose of which is to prevent passing therethrough particles of earthor rock too large to pass through the opening herein described in themachine. The gold with the sand, gravel and water is discharged into thedistributing tank 5 on either side of a battle partition 8 whichprojects partly across the face of the distributing tank. Thisdistributing tank is provided with an inclined Specification of LettersPatent.

bottom, the inclination of which is in the direction of the longitudinaldischarge port 9 through which the substance operated on passes ontooscillating screen l0. This screen has an inclination downwardly fromthe point- 11 immediately under the discharge opening 9 where thesubstance is received, which passes thence along the inclined face ofsaid screen to the bottom 12 thereof. At this point the particles toovlarge to pass through the mesh in the oscillating screen will pass overthe ledge 18 and into the discharge trough 14 and pass thence out of themachine into the water in which the separator is stationed, the finerparticles including all particles of gold will pass through theoscillating screen into the longitudinal V- shaped trough 15 and passout at the bottom thereof through the discharge port 16.

To properly distribute the substance passing through the apparatus Ihave provided an adjustable cover 17 for placement along and over thedischarge opening 16. This cover is provided with means to increase anddecrease the width of the discharge opening 16 by means of set screws18, a handle 19 being provided to hold the cover in any desired positionwhile regulating the opening to the port 16. The substance operated uponpassing out through the slotted port 16 drops upon the amalgam plate 20,the inclination of which will carry the particles not adhering to theplate down upon the burlap 21 and thence downward over the inclinedburlap table and be discharged (less particles adhering to the burlap)into the water as at 22.

To operate the oscillating screen l0 I have provided the counter-shaft23 carrying driven pulley 24E keyed thereto. This pulley is rotated bythe belt 25 passing over the pulley 26 keyed upon the driving shaft 27.This counter-shaft carries a cam 2S which is keyed thereon, on therotation of which will together with the action of the coiled spring 29impart an oscillating motion to the oscillating screen 10.

Having described my invention what I claim as new and desire to secureby Letters Patent is 1. In apparatus of the class described, incombination, a distributing tank having a longitudinally extendingoutlet, means for directing a current of water carrying the gold in adirection extending longitudinally of Said Outlet, a battle adapted todivide said current and aording means for guiding aA portion ,thereoftoward the remote part vof i said outlet, and separating means receivingthe gold bearing current beyond said-outlet.

2. In apparatus of the class described, inA combination, a distributingtank ihaving -laf baffle Wall and having an koutlet below the: level ofsaid Wall, means for directing a current of Water carrying the ,goldalong said bafie so that said baiile divides said current and guides aportion ofsaid current along the interior of said tankand a goldseparator receiving l:the gold bearing cnrrentater passing saidoutlet,'said tank 'having a bottom inclined transverselyto said'baiiie.

3. tIn apparatus of 4the class described, in combination, a distributingtan'lr having an inclined bottom, said bottom having a slot gold in adirection longitudinall.

at the 'lower "part thereof extending longitudina-lly of said tank, abaflie Wall extend- -i-ng longitudinally -o said tank, :means fordelivering a current of Water carrying the of said `baffle Wall so thatsaid baHe Wal divides said current, said baliie affording means fordirecting the uppermost of said currents toward the remote end of saidtank, a gold separator and means for directing the cur,- rent from saidoutlet on to said amalgamating plate.

`1n .Witness that I claim the foregoing have hereunto `subscribed myname this 19th day Vor Decem'ber, '1908.
